The given values force the following behavior of the SAA7118 audio clock generation part:
•
•
•
•
•
•
Used crystal is 24.576 MHz
Expected field frequency is 59.94 Hz (e.g. NTSC M standard)
Generated audio master clock frequency at pin AMCLK is
256 kHz
AMCLK is externally connected to AMXCLK [short-cut between pins P11 (72) and
M12 (76)]
ASCLK = 32 kHz
ALRCLK is 44.1 kHz
44.1 kHz = 11.2896 MHz
